sub-par at best
Crutchfield Customer Review (What's this?)
I bought 3 of these because I could not find another battery connector with a built in fuse. Also purchased StreetWires 4-gauge Crimp-on 3/8" Power Rings. I thought these two items would match perhaps because they both include the phrase "Power Ring". But power ring hold down screw bottoms-out on the plastic prior to tightening by significant amount in other words the power ring connector needs to be 3 times as thick. Spend time grinding the length of threads down. The surface area/meterial of set screws allen key head appear as if you could tighten them only once before stripping the head. As long as you can then grab onto the head with side cutters or pliers you could work with it, but I am concerned that stripping the head of the in-set screw would be disastrous, but I'm only using the power ring. 1 of the 3 I purchased, the plastic cover was warped suchas the snaps that hold it in place don't touch the mating surface. 1 screw had a lot of play even when threaded halfway in by hand. I purchased and kept this ONLY due to its unique FEATURE of having a fuse, not its general quality of construction and durability. Sorry, but that's my evaluation opinion. Yours may be different.
